Rice transplanter is characterized by the relatively simple structure, relatively easy operation, the operator only simple training, you can manipulate the transplanter. Graduation Project in accordance with the requirements of the form as a result of the work of Rice Transplanter with the purpose of this design is similar, it will be for the prototype rice transplanter.Key words: The cabbage transplanter；Transplants the arm； Divides transplants rice seedlings the principle；Divides transplants rice seedlings the organization目錄- 3 -摘要 .IIABSTRAT III前言 11 概述 21.1 課題研究的目的 .21.2 國外蔬菜栽植機械發(fā)展現(xiàn)狀 .31.3 國內(nèi)白菜移栽機械現(xiàn)狀、發(fā)展及存在的問題 .41.3.1 國內(nèi)白菜移栽機械現(xiàn)狀 .41.3.2 目前主要研究成果 .41.3.3 國內(nèi)水稻插秧機械存在的問題 .51.4 白菜栽植機的研究和發(fā)展 .61.5 白菜移栽機栽植臂涉及內(nèi)容和方法 .62 PRO/E 模塊簡介 .72.1 Pro/Engineer 功能及特點 72.1.1 Pro／Engineer 72.1.2 Pro／ASSEMBLY 82.1.3 Pro／CABLING .82.1.4 Pro／CAT .92.1.5 Pro／CDT .92.1.6 Pro／CMPOSITE 92.1.7 Pro／DEVELOP .92.1.8 Pro／DESIGN .102.1.9 Pro／DETAIL .103 栽植臂的工作過程 .104 分插秧原理與分插機構(gòu)的設(shè)計 .114.1 設(shè)計內(nèi)容和步驟 114.2 分插機構(gòu)組成 114.3 分插工作原理 124.4 秧爪 124.4.1 秧爪的設(shè)計 124.4.1 秧爪排運動機構(gòu)的設(shè)計 164.5 曲柄連桿的組成及工作原理 164.6 曲柄連桿的設(shè)計 185 栽植臂的組成與設(shè)計 .195.1 推秧擺臂的設(shè)計 205.1.1 推秧擺臂運動規(guī)律的選擇 205.1.2 推秧擺臂的設(shè)計尺寸 215.2 推秧凸輪的設(shè)計 21- 4 -5.3 栽植臂體的設(shè)計 245.4 栽植臂的運動分析 24圖 11 栽植臂的運動分析圖 25總結(jié) .26結(jié)束語 .27致謝 .28參考文獻 .29附錄Ⅰ .30附錄Ⅱ .31
